A suicide bomber struck a military facility in northwestern Pakistan, killing at least 31 soldiers and wounding more than 40 others.
Pakistani authorities say the soldiers were busy in their early training session in Mardan, when a teenage bomber dressed in a school uniform walked up to them and detonated the explosives.
The powerful blast is said to have instantly caused most of the deaths. Doctors fear the toll could rise because some of those wounded are in critical condition.
Witnesses say several schools are also located near the military base, called Punjab Regiment Center.
